FIELD: electrochemical processes, methods of active aluminum oxide production used for production of complex catalysts for hydrogenation processes. SUBSTANCE: aim is to speed up process of product, significantly to decrease formation of waste waters, to increase qualitative characteristics of product, to decrease usage of settling reagents and solvents. To realize the aim method of active aluminum oxide production provides for dissolving of alumina in acid or alkali with following settling of aluminum hydroxide exercised in one of electrolyzer chambers under electric current density of 5 - 30 A/sq dm, temperature of 80 - 90 C and 6≅pH≅12. EFFECT: method allows to speed up process of production, to decrease formation of waste waters, usage of settling reagents and solvents, to improve quality of product. |
